A huge majority of projects are fated to doom. Due to the simple fact that 99% of project tokens are useless, and add to the fact that most businesses and startups in general fail inside and outside the cryptocurrency space. So if you're thinking that crypto investing is easy, nope.
This is the reality not just in crypto, but even outside crypto. Everything is associated with risk. And since no project that will guarantee profits, if they cannot succeed, meaning they will end up failing. Even bitcoin does not guarantee profits after all, we only know it will continue to grow its value, but we don't know when will it last, so everything may still end up to doom.
